Steven Universe has been hailed as one of the most inclusive, queer-friendly shows of all time.

In fact, in last week’s episode, two same-sex protagonists got engaged. The episode is the first time a same-sex proposal has been seen on a mainstream children's show.

But that’s not all the exciting news for Steven Universe fans. The show’s creator, Rebecca Sugar, just came out as non-binary. They revealed their identity is partly what contributes to the non-binary identity of the show's protagonists, but it was the show itself that allowed Sugar to become more open in discussing their own identity publicly.

“One of the things that’s really important to me about the show is that the Gems are all non-binary women. They’re very specific and they’re coming from a world where they don’t really have the frame of reference. They’re coded female which is very important. I was really excited because I felt like I had not seen this. To make a show about a young boy who was looking up to these female-coded characters—they appear to be female, but they’re a little more representative of nonbinary women.

They wouldn’t think of themselves as women, but they’re fine with being interpreted that way amongst humans. And I am also a non-binary woman which is been really great to express myself through these characters because it’s very much how I have felt throughout my life.”
